Hello,

I am looking for information about garbage collector. I already looked at documentation but I could not find anything about it.
Here is some questions :

1) is there a garbage collector per process (each process has it's own memory and GC is done per process) or is it global (eg: shared memory) ?
I know there is some memory allocated per process at startup but also globally (gmheap).
2) when a GC / cleanup occurs somewhere,  is it possible that it block the other processes for a short moment ? (eg: a "stop the world" GC that pause everything while job is being done).
3) is it possible to

Hi,

     I am trying to load all the data tables from one iris server to a client server but some of the tables data failing to load all the time. But I can load around 100 tables successfully  but 8 to 10 tables are failing all the time. I made an IRIS odbc connection using odbc driver to load the data from tables.

Also I can see read server loop error message on the iris server side as the same time the table loading fails.

Please find the screen shot attached which shows the error on client server.

Can anyone provide me an advise how to fix the issue.

Thanks

Iris DAT file is filling up  the Internal Storage with available Free Space to Zero. Is there any Alternative measures to reduce the File size or to control the Capacity.  Is there any chance to save Local storage. 

Once the Local Storage is full, Production is not responding and throwing Out of Space Error.

Does IRIS has any Internal Cloud Storage which can be used for managing and Storing  Database Operations. If yes, How can we configure it,

I am trying to setup our first SSL/TLS configuration so we can possibly connect to the EMR FHIR server to pull data into the Interoperability engine.

I am running on Red Hat, and created and submitted a openssl CSR request to our Windows ADCS system.

I used the following command to generate the key and CSR request to submit to Windows ADCS

openssl req -new -sha512 -nodes -newkey rsa:4096 -keyout xxxxxxx.key -out xxxxxxxx.csr

When the certificate was generated I was able to download the individual certificate (cer) and the certificate chain (p7b) in  DER or Base64.

This is a bit of an IRIS question but also and OAuth 2.0 questions:

I am using %OAuth2.JWT.JWTToObject() to "validate" a JWT.  My questions:

- While I am checking claims with the returned body, does the return status of the method "count" as a validation step? In other words, if I weren't checking claims and $$$OK was returned from that method call (passing in the token and public keys), I could feel confident that this token came from the expected auth server?

- Does the method or can it validate the token expiration or is that something I need to manually validate; token expiration seems

When manually coding REST services and using GET /api/mgmnt/v1/:namespace/spec/:application/ to return an OpenAPI spec, how do you specify supported properties (OpenAPI Properties in Use | Creating REST Services | InterSystems IRIS Data Platform 2021.1) like responses, definitions, and information in paths like summary and description?

GET /api/mgmnt/v1/:namespace/spec/:application/ | Creating REST Services | InterSystems IRIS Data Platform 2022.2

Using a very basic manual REST service that returns a JSON string I get a pretty basic spec that is not really helpful when it comes to documentation.

I have the following setup: REST broker calls inProc BO via BS. As BO initialization is time-consuming, I want to reuse the same BO during the CSP process lifetime.

I have tried the following approaches:

1. Set %session.Preserve to 1 (I would prefer not to use it as the BO object is not linked to a specific client)
2. Set $$$EnsInProcPersist to 1 (looked relevant)
3. Cached BS between calls

However, every time I call my REST endpoint, I get a new BO. Is there a way to cache inProc BOs in the CSP context?

To run the sample, import it into any interoperability-enabled namespace, start in.Production pro

Hi InterSystems Community

We recently had an issue where we weren't able to parse a JSON HTTP request, but the issue went by unnoticed. We also did not have a trace of what the raw HTTP request was that we couldn't parse. I'm looking at improving our this by:
Tracing the raw request using $$$TRACE

Raising an alert which will hit our Ens.Alert router which will compose and send an email

I'm having an issue with consistently raising the alert (I've seen it raise an alert before, and then it wouldn't raise it again on a subsequent message), and also the error back does not really make sense.

The InterSystems documentation https://docs.intersystems.com/irislatest/csp/docbook/DocBook.UI.Page.cl… says: "If you do not already have these files, contact the InterSystems Worldwide Response Center (WRC) for download information."

Hibernate is the most used framework to do database persistence. All databases in the market allows get hibernate driver in public repositories, InterSystems no. It is a barrier to InterSystems adoption in the Java Community.

When InterSystems will provide Hibernate jar file to public download, into a public maven repository? 

Any news about JDBC driver and Hibernate dialect on a public java repository, like mvnrepository? Today I need to download the jdbc driver and hibernate jar, add as an external resource on my maven config file to works.

Good morning!

I am developing a Java project (Spring Boot + Maven + Hibernate) but I've a big issue when I try to define the Hibernate Dialect org.hibernate.dialect.InterSystemsIRISDialect... that dialect is neither in the Hibernate library nor in the IRISDriver class com.intersystems.jdbc

How should I define the IRISDialect in my project?

Thank you in advance!

I am hoping someone can let me know if I've gone down a dark path or not:

• I'm using the record mapper to create a business service that waits for a .txt file and sets pipe delimited data to the mapper's record class
• That record (essentially the raw data) is sent to a business process 
  • OnRequest() is implemented where it opens or creates an instance of the target object and validates and transforms and sets the data to the target object as needed; the response is that target object.
  • OnResponse() is implement as a shell and simply returns $$$OK
• The goal is simply to update or create

InterSystems announces its sixth preview, as part of the developer preview program for the 2023.2 release.  This release will include InterSystems IRIS and InterSystems IRIS for Health.

Highlights

Many updates and enhancements have been added in 2023.2 and there are also brand-new capabilities, such as Time-Aware Modeling, and enhancements of Foreign Tables (but still as an experimental feature). Note that some of these features or improvements may not be available in this current developer preview.

Another important topic is the removal of the Private Web Server (PWS) from the installers.

Hi all,

 I'd like to start playing around with some simple Angular app with IRIS REST Api but I'd like to do so in the best way possible, did you have any best practices and/or VSCode setup to make life easier? 

Keep in mind I've never developed an Angular APP before, so also some simple example will be really useful.

Tnx.

A community helper class was implemented should people need this. ( alwo.EnsHelper.HostRequestResponseInfo )

Install

I have created a global say ^myglobal and entered some data. I am storing the name of global in databases and fetching the name based on some criteria. I am getting "^myglobal" in return from databases but i am not able to fetch the data I stored in the global. 

I tried set var = result.global which gives me "^myglobal" in var. Doing WRITE var will return "^myglobal" and not the data i stored in this global.

It can sometimes be useful to list or export all of the subclasses that are derived, directly or indirectly, from a given class. In Studio, the Class -> Derived Classes menu option will show such a list, but I'm not aware of a built-in API for programmatically exporting their source code.

Yesterday I wrote some code for exporting derived classes, and I'm thinking about cleaning it up and putting it on Open Exchange.But if there's a simple way to do this that someone has already figured out, I'd be happy to know about that (and help others find that solution) rather than reinventing the wheel.

As previously announced at Global Summit 2022, InterSystems will discontinue shipping or installing an Apache-based web server (often referred to as the private web server or PWS); this change is currently planned for InterSystems IRIS 2023.2. 

With this new approach, you have full control to choose which web server best suits your purposes, and how you configure, maintain, and update it.A key benefit of this change is that you will no longer have to wait for an updated kit from InterSystems to get the latest version, which is important especially in security vulnerability situations.

Starting in version 2021.1, InterSystems IRIS began shipping with a python runtime in the engine's kernel. However, there was no way to install packages from within the instance.

Hi devs!

How one can understand the classnames of request and response messages of a given operation?

E.g. when I build the data transformation, how do I know which message will come to the operation?

Now the Classes/Rutines/DeepSee files will be automatically exported to the working directory after saving or compiling and files will be automatically deleted .

Installation

To install isc-dev , you just need to download and import the file isc-dev.xml from last release. Some ways to import isc-dev .xml file:

• Go to Management Portal -> System Explorer -> Classes -> Import and select the XML file.
• Drag the file over Studio.
• Terminal command:

NS>do $system.OBJ.Load("yourpath/isc-dev.xml","ck")

• Get it from Package Manager Client:

NS>zpm
zpm: NS>install isc-dev

How to enable this feature:

• After importing the class in the target namespace, run the following method to set up the working directory:

NS>do ##class(dev.code).workdir("/path/to/your/working/directory/src/")

• Go to Management Portal -> System Administration -> Configuration -> Additional Settings -> Source Control.
• Select the target namespace and set the dev.FileManExtension class as the main one and save it.
• Try to create a new class in the studio and save/compile it
• Enjoy!
